The specs say there is less so many were concerned the new “greener” D4 battery just wouldn’t deliver. This past week I pounded the D4 bigtime with the biggest day being nearly 98GB of capture, still & vid combined. I mentioned I rented two batteries to CYA only to never use them. The D4 battery never went dead on me after a day’s use delivering the same performance I was use to with the D3. So with shooting and chimping and AF operation, the new battery didn’t let me down.
